Holt-Oram Syndrome, well described by Holt and Oram in 1960, is an autosomal dominant disorder consisting of upper extremity and cardiovascular anomalies with variable expression. A typical case of this syndrome was experienced by authors recently and is to be presented with review of literatures.

Previous studies reported that oxaliplatin is associated with sinusoidal obstruction syndrome. However few reports on oxaliplatin induced liver fibrosis are found in the literature. Furthermore pathogenesis of liver fibrosis is not well known. We report a case of 45-yr-old Korean man in whom liver fibrosis with splenomegaly developed after 12 cycles of oxaliplatin based adjuvant chemotherapy for colon cancer (T4N2M0). Thorough history taking and serological examination revealed no evidence of chronic liver disease. Restaging CT scans demonstrated a good response to chemotherapy. Five month after chemotherapy, he underwent right hepatectomy due to isolated metastatic lesion. The liver parenchyma showed diffuse sinusoidal dilatation and centrilobular vein fibrosis with necrosis without steatosis. We could conclude that splenomegaly was due to perisinusoidal liver fibrosis and liver cell necrosis induced portal hypertension by oxaliplatin. In addition, to investigate the pathogenesis of liver fibrosis, immunohistochemical stains such as CD31 and alpha-smooth muscle actin (alpha-SMA) were conducted with control group. The immunohistochemical stains for CD31 and alpha-SMA were positive along the sinusoidal space in the patient, while negative in the control group. Chemotherapy with oxaliplatin induces liver fibrosis which should be kept in mind as a serious complication.

Many authors have been reported that the abdominal trauma, especially injury of the liver and spleen, is frequently found with lower rib fractures, below the ninth rib fractures and the incidence was about 20 to 30%. In cases of rib fractures, Intra- abdominal organs may be injured in the higher rib fractures than the ninth because the diaphragm is elevated at the level of filth intercostal space in expiration period and the intra-abdominal lesions are often delayed evaluated due to the pain of the fractures and masked by the other injuries of the head and the extremities. So above reasons, we were often questioned what the level of rib fracture we must evaluate the intra-abdominal injury was? So we investigated 452 patients with rib fractures who visited our emergency medical center from 1995, January to 1996, December and divided into two groups according to the prescience of intra-abdominal organ injuries by each the level of rib fractures. The number of patients with intra-abdominal organ injuries were 75(16.6%) and the most frequently damaged organ was the liver(25 cases, 33.3%). We calculated the statistical values of each level of rib fractures by the Chi-Square method and got a result that the level of rib fracture we must evaluate the intra-abdominal injuries was the sixth rib fracture. Therefore, if we will meet the patients with rib fracture below the sixth, we must have attentions to the intra-abdominal injuries and evaluate the abdomen closely with various diagnostic methods.

STUDY DESIGN: Retrospective case series. OBJECTIVES: We retrospectively evaluated the clinical efficacy of postganglionic nerve block in symptomatic Schmorl nodules (SNs). SUMMARY OF LITERATURE REVIEW: SNs are common lesions that are often asymptomatic. In certain cases, SNs have been reported to cause severe axial back pain, thereby considerably impacting patients' quality of life. No consensus currently exists on the treatment of symptomatic SNs. MATERIALS AND METHODS: From October 2015 to October 2017, a total of 21 patients with symptomatic SNs diagnosed by magnetic resonance imaging (MRI) that did not respond to conservative treatment after 4 weeks were included in the study. All patients received postganglionic nerve block. We evaluated effective pain relief (improvement of back pain of more than 50% compared with before the intervention) and functional improvements, assessed by visual analogue scale (VAS) and Oswestry Disability Index scores obtained at 4 hours, 4 weeks, 8 weeks, 3 months, and 6 months after the procedure. RESULTS: Symptomatic SNs were more common at the L2-3 level, and the lower end plate was more commonly involved than the upper end plate. Eighteen of the 21 patients (85.7%) showed effective pain relief, and no deterioration was observed within the follow-up period. Throughout the follow-up period, the VAS remained significantly improved compared to before the procedure (p < 0.05). Complications were not reported in any cases. CONCLUSIONS: Postganglionic nerve block for symptomatic SNs that do not respond to conservative treatment is a non-invasive modality for pain relief.

Objectives: Gastric dysplasia is primarily treated using endoscopic resection. Although argon plasma coagulation (APC) is an alternative treatment for older patients or those with bleeding tendencies, studies have reported a higher rate of local recurrence after APC than after endoscopic resection. Using pathological examinations, this study aimed to investigate the incidence and associated causative factors of residual dysplasia following APC. Methods: This prospective study recruited patients with low-grade gastric dysplasia from March 2020 to February 2021 and conducted follow-up examinations for 15 months after enrollment of the last patient. The patients were randomly assigned to undergo APC at an output power setting of 45, 60, or 80 W. Results: Residual lesions were found in 13 of 68 patients (19.1%) during the 24-h follow-up endoscopy and biopsy. The Ki-67 index, a marker of cellular proliferation, was significantly associated with the presence of residual lesions. The presence of residual dysplasia at the three-month follow-up was associated with the presence of residual lesions at the 24-h follow-up and a positive Ki-67 index. Only three of the 13 patients with residual lesions 24 h after APC demonstrated residual lesions at the three-month follow up. No post-procedural complications were observed. Conclusions Residual dysplasia may persist even after APC and cause local recurrence. If Ki-67-positive cells are detected in the remnant tissue following APC, additional interventions should be considered.
